• 10.1 Methodology
• 10.2 Research Process and Data Source

The global Seawater Battery market size is expected to reach $ 2860 million by 2032, rising at a market growth of 22.9% CAGR during the forecast period (2026-2032).
Seawater batteries utilize magnesium alloy as the anode and carbon fiber materials as the cathode, directly employing seawater as the electrolyte and dissolved oxygen in seawater as the oxidizing agent. Featuring an open-circuit design requiring continuous seawater flow during operation, they offer simplicity, high energy density, and unlimited dry storage time. The only consumable material is the metal anode, though their power output remains relatively low.
Global seawater battery sales reached 3,043 MWh in 2024, with an average selling price of $185/kWh.
Application Development
Marine Energy Sector: Seawater batteries operate stably in marine environments, providing reliable power and energy storage systems for tidal and wave energy facilities, thereby enhancing energy utilization efficiency.
Deep-Sea Exploration Sector: Their long lifespan and corrosion resistance make them ideal power sources for deep-sea exploration equipment, such as underwater robots and seafloor seismic monitors, enabling prolonged continuous operation in deep-sea conditions.
Marine Engineering Applications:
For large-scale projects like offshore wind farms and marine oil/gas platforms, seawater batteries meet stringent requirements for power stability, reliability, and environmental sustainability. They deliver green, sustainable energy solutions for marine engineering while reducing operational and maintenance costs.
Other Applications:
Seawater batteries also serve as emergency and backup power sources at sea, power subsea navigation systems, and more. With ongoing technological advancements, their application scope is expected to expand further.
